Tft active matrix.Advantages and disadvantages of tft screen and other information. With the change of the times, people’s living standards are also constantly improving. In the past, landlines were used. With the development of science and technology, people began to use mobile phones and computers.

Mobile phone screen will also continue to improve with the progress of the times, now the most widely used is the tft screen, of course, there are many different models of different materials of the screen, such as IPS screen, what are the advantages and disadvantages of TFT screen, follow the editor to understand the advantages and disadvantages of tft screen.

TFT (Thin Film Transistor) is a thin film field effect transistor, which can “actively” control individual pixels on the screen, which can greatly improve the reaction time. General TFT reaction time is relatively fast, about 80 milliseconds, and the visual angle is large, generally can reach about 130 degrees, mainly used in high-end products. Thus, the screen information can be displayed with high speed, high brightness and high contrast. TFT belongs to active matrix liquid crystal display, which is driven by “active matrix” technology. the method is to use the transistor electrode made by thin film technology, and the scanning method is used to “actively pull” to control the opening and closing of any display point. when the light source is illuminated, it first passes through the lower polarizing plate, conducts light with the help of liquid crystal molecules, and achieves the purpose of display through shading and transmission.

The main components of TFT LCD include: fluorescent tube, light guide plate, polarizer, filter plate, glass substrate, alignment film, liquid crystal material, thin mode transistor and so on.

With the gradual popularity of mobile phone color screen, the material of mobile phone screen is becoming more and more important. The color screens of mobile phones vary according to the quality of LCD and the technology of research and development, including TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors can be displayed, the more complex the image can be displayed, and the level of the picture is also richer.

TFT–ThinFilmTransistor thin film transistor is one of the active matrix type liquid crystal display AM-LCD. TFT sets a special light tube on the back of the liquid crystal, which can “actively” control each independent pixel on the screen. This is the origin of the so-called active matrix TFT (activematrixTFT), which can greatly improve the reaction time. Generally, the reaction time of TFT is faster, about 80ms, while STN is 200ms. If you want to improve, there will be flicker. And because TFT is an active matrix LCD can make the arrangement of liquid crystals memorable and will not return to its original state immediately after the current disappears. TFT also improves the STN flicker (water ripple)-the blur phenomenon effectively improves the ability to play dynamic pictures. Compared with STN, TFT has excellent color saturation, restoration ability and higher contrast, but the disadvantage is that it consumes more power and costs more.

TFT LCD is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by a point pulse, so each node is relatively independent and can be controlled continuously, which not only improves the reaction speed of the display screen, but also accurately controls the display color levels, so the color of TFT LCD is more real. TFT LCD is characterized by good brightness, strong sense of layering and high degree of reduction, but it also has the deficiency of power consumption.

SLCD is the abbreviation of English Splice Liquid Crystal Display, that is, splicing special LCD screen. SLCD is a high-grade derivative of LCD. SLCD is a complete splicing display unit, which can not only be used as a display, but also can be spliced into a super-large screen. According to different needs, realize single screen segmentation display, single screen separate display, arbitrary combination display, full screen splicing, vertical screen display, image frame optional compensation or masking, full HD signal real-time processing.

AMOLED is a kind of OLED technology. AMOLED (Active Matrix/Organic Light Emitting Diode) is an active matrix organic light emitting diode panel. Compared with the traditional liquid crystal panel, AMOLED has the characteristics of faster response speed, higher contrast, wide viewing angle and so on.

Super AMOLED (full name: Super Active Matrix/Organic Light Emitting Diode) super dazzling screen, compared with the traditional AMOLED dazzling screen, abandoned the previous touch sensor layer + display layer architecture design, the control is more sensitive. In addition, the removal of the glass cover also brings a better display in the sun. At the same time, Super AMOLED is also equipped with mDNIe (Mobile Digital Natural Image engine) technology that can watch and respond quickly from any angle.
